    Posted: February-02-2016 at 8:59pm
I recently bought a 1980 Correct Craft Ski Nautique dirt cheap. The only catch is the boat needs an entire stringer and floor rebuild. When i say the stringers are completely rotten, it is an understatement. I'm worried while removing the old stringers from the boat they are just going to fall apart making it a nightmare to make a clone of them for the new stringers I will be replacing them with. I was wondering if any of y'all have any stringer specs or any other measurements in general that could make my life any easier. Or if you know of any existing threads of good rebuilds on similar Nautiques, if you could point me in that direction that would be awesome.

Any help would be greatly appreciated.

Connor,
Get as many measurements as you can. Width between stringers and height are the critical ones. Take pictures too (we'd love to see them as well). Many have been through the same as yourself and found it's not that bad to figure what goes where.

Welcome to CCfan. You'll find some great threads on just about anything including stringer jobs. The FAQ thread in the maintenance section is the place to go.

The main dimensions are the engine location & pylon. Get those right & the other points will fall into place.

I got the exhaust off and prepped the motor to be pulled but this being a boat from florida and driven in saltwater all the bolts on the motor are rusted. I soaked some rags in PB Blaster today and left them sitting on the bolts. Hopefully it should loosen them up because i don't really wanna have to cut them out risking damage to the brackets. Besides the motor i started dripping up sections of the floor to see how bad the stringers and bulkheads are underneath....... Yeah it wasn't pretty. Here's some pictures of the boat for y'all that have been asking.

Connor,
You have fallen for the BS advertising hype with the PB! Go for the scientific facts and not what's written on a can. "as advertised on TV" is always a dead on indication that a product is C***. If I remember correctly, Billy Mays at one time was pushing the stuff!

Here's the list of torque requirements copied from another thread:

Penetrating oil ..... Average load

None ...................... 516 pounds

WD-40 ................... 238 pounds

PB Blaster ............... 214 pounds

Liquid Wrench ......... 127 pounds

Kano Kroil .............. 106 pounds

ATF-Acetone mix.......53 pounds

I don't even consider WD40 to be a penetrating oil so that puts PB at the bottom for me. Kroil is a on line order only so when I was taking my 1927 Flexifour apart and trying to break the rusted pistons loose, I did pick up a can of PB. A week went by with no luck and then the Kroil came in. The next day after using some of the Kroil, all four pistons were loose. I ended up using the PB as a honing lubricant!


Go for the 50-50 home brew. It works as many including myself have found out.

And the PB Blaster smells really bad anyway.   I wouldn't want that stench in my boat.

50/50 ATF/Acetone is truely magical.

The ATF and acetone is probably the cheapest and easiest to use, but the Kroil is amazing as well. I used it on my broken riser bolts and they came right out after soaking them for a day or so.

I noticed a hole in both of the stringers in 85 nautique today, they are both below rear engine mounts. I am not familiar with stringer repairs so I was hoping for some advice. I don't know how severe this is and if I should do a patch job to get through the season? here are some pictures of the holes.

I believe that allows water to drain from the other side of that stringer to the center, and out of the boat.

that is what i thought when i noticed them on both sides and with that location it makes sense but would they not have sealed that from rot as well? i can feel rot it the holes doesn't seem likes it is eat up too much though??

I would start your own thread or piggy back on one of your prior ones. I can't help you other than knowing mine has similar holes. They guys with much more experience will help you but I bet you will get more help if you start your own thread and say more about the general condition of your stringers and boat.

It quite possibly could have been sealed when the boat was made. The fiberglass around the hole probably rotted and cracked along with the wood in the stringers. Giant chunks of fiberglass are missing around on my stringers.

At times, CC didn't give much thought to preventing water getting into the wood stringers!! When replacing stringers, it's suggested to cut a half round notch for the weep holes and then fully glass the cut out. CC probably at best slopped some resin in the weep holes.

Floors and foam up, taking out the stringers this weekend.

I guess the fiberglass department at correct craft liked their Ruffles and Jack Daniels. Has anyone else found food and sh it in their factory foam?

take a look at the cross section and you will find the answer   
2 completely different foams are showing , likely an old repair

Steve,
Thanks, now I see the different foam. To me it looks like a repair was made forward from about the engine. Probably just the plywood sole for the front seats. You'd make a great detective! Seeing that Jack label, I was going to ask Art who it was at the factory that drank the stuff! I'm glad the label turned out to be post factory days. Looks like Conner's boat has had a pretty rough life as it's one of the worst I've seen.

Conner,
Your haven't mentioned anything about the engine. How's it's condition? Keep the pictures coming. I feel your stringer job will be a valuable addition to the others here. What are your intentions? Wood? Composite? Epoxy? Fill us in.

I actually worked as a carpenter putting in stringers and all other structural work at a boat manufacturing company right out of high school and we used Coosa Board, so that was my original plan. Although I just do not find it necessary for this build. Besides the fact that Coosa Board and similar composites are stupid expensive this boat lasted 36 years with wood stringers I think it should be fine to give it another go with the same materials. Plus I think I am gonna do a little better job trying to seal off the wood from moisture the CC did. Also my main use for this boat will be wakeboarding and wood does weigh more than composite therefore bigger wake(also with the added ballast bags of course).
